RUPTURE DISC AND DISTRIBUTOR WITH GAS INSULATION CONTAINING IT Russian patent published in 2015 - IPC F16K17/40 F16K17/16 

FIELD: machine building.

SUBSTANCE: group of inventions relating valves manufacturing and intended for use as the rupture disc in safety devices to protect HP systems. The rupture disc for the distributor with gas insulation contains thin domed plate that contains first flange part and first domed part at centre of the first flanged part, and rupture guiding plate containing the second flanged part overlaid on the first flanged part, and second domed part with number of slits created such that to determine the rupture shape such, that part of the first domed part will rupture as per specified shape when the internal pressure increases. The slits have arc-like shape. One single clit is connected with the another single slit adjacent to it by means of the rupture link. End sections of the clits at both edges of the multiple clits are provided with rupture limiting holes to create the articulated part of the second domed part. The design option of the rupture disc and distributor with gas insulation containing the rupture disc is available.

EFFECT: invention improves reliability and accuracy of activation of the rupture disc.
